    Yeah, hit it with the heat big time. Super clean material, tight fit, electrode angle are all key.
    For the flush fit you mention I would probably have the electrode roughly parallel with the disc, pushing the pipe material towards the disc with the arc.

      Hey Reggie...We get your point without a doubt
      But rather than burning yourself up with this, when we all know you obviously have good knowledge to contribute, why not let it go?
      You are just skirting the edge of forum rules if not disobeying them and it generally ruins the entire mood here and really does not make you any real friends either.
      It is one thing to make a snide comment here or there but to dig up old threads and call someone out is actually nothing more than harrassment plain and simple. No matter who started it, and I doubt anyone cares it is beginning to get out of hand now.
      If Monte wants to watch Hawks or raise flowers and post about it then it just shows maybe we could have an off topic section.
      I spend enuff time on here I have grown to respect the opinions of many members on a broad variety of subjects besides just welding. Monte is simply sharing his. There are a ton of threads I simply do not read because I have no interest in them.
      So as nothing other than just one forum member to another....could you just let this go PLEASE and help keep the peace here at miller?? We have already had enuff drama here for several forums

        Hi Nick,

        I did these aluminum cubes in almost the same way as your round tube setup.

        The material is 1/8" thick and the finished cubes are 3 1/4" on each side.

        Since the material is 3" wide, I cut the pieces 3" long.

        Tacked the 4 sides together leaving a 3" x 3" opening for each "plug"

        Then I had to figure out how to keep the plug from falling in.

        Used a small 2" diameter rod and a stack of washers inside to get the aluminum plug to end up 1/8" higher than the sides.

        Then used filler rod to do an outside corner weld which was easier for me to do.

        So it is not exactly like your situation.

        If I had to do your weld, I would have the round plug stick up above the edge of the pipe and do the same outside weld with filler rod.

        Oh, had to drill the vent hole after I messed up the first one as it was not vented.

        Good luck

          Good post FK, and all true but...................it gets to the point where guys like monte start acting like a bit of a sissy and to be completey honest, he isn't without blame here. He has been preaching for a long time about just letting things slide and not posting if you don't have anything good to say. Then, he has been the one fanning the flames and doing EXACTLY what he tells other members not to do. Hypocritical at the very least and highly instigative at best. He's creating a lot of this himself but trying to make it out like he's the good guy. Total BS.

            Call it a tack, or call it a weld but trying to join two pieces of aluminum without filler will always result in a weld that is weaker than one in which filler was added. Not only do they often crack, the weld itself is just not as strong.

            What's the problem with adding a little filler. Dang stuff is really pretty cheap.

            Stainless steel, on the other hand, will fuse nicely without filler if the joint is prepared properly.
